3 Planets That Shouldn't Exist

The video explores three mysterious exoplanets that challenge current astronomical theories. Kepler 78 B is a rocky planet with Earth-like density but orbits its star extremely closely, defying formation theories. Kepler 10C, dubbed a 'Mega Earth,' is unexpectedly dense and lacks a thick atmosphere. HD-106906 B is a massive gas giant orbiting far from its young star, raising questions about its formation. These planets highlight the gaps in our understanding of planetary formation and the universe's complexities.

What is the main reason scientists are puzzled by the existence of Kepler 78 B?

• Its similarity to Earth

• Its large distance from its star

• Its gaseous atmosphere

• Its close proximity to its star

How long does a year last on Kepler 78 B?

• 8.5 hours

• 30 days

• 365 days

• 24 hours

What nickname was given to Kepler 10C due to its unusual characteristics?

• Mega Earth

• Mini Neptune

• Tiny Titan

• Super Jupiter

Why is Kepler 10C's mass surprising to scientists?

• It is too small for its size

• It lacks a gaseous atmosphere

• It has a thick atmosphere

• It is too light for its size

What is unusual about HD-106906 B's orbit?

• It has a circular orbit

• It orbits multiple stars

• It is extremely far from its star

• It is very close to its star

What is one hypothesis about how HD-106906 B ended up in its current orbit?

• It formed in its current position

• It was kicked out from a closer orbit

• It formed from a nearby asteroid

• It was captured by another star

What is the main theme of the video regarding the study of exoplanets?

• Exoplanets are not important to study
